Fix(input): validate contradictory final parameters

[Stardust0831]

Summary

• require explicit nspin=4 for noncollinear and spin-orbit calculations instead of silently resetting it
• accept nbands_sto only as an integer from 1 to 100000 or all, without changing esolver_type
• validate the final kpar/bndpar/solver configuration instead of resetting or clamping bndpar
• update affected examples, regression inputs, and generated parameter documentation

These checks use the existing final check_value phase, after parameter finalization, without adding reset ordering or dependency machinery.

Refs #7719.

Tests

• four focused CTest targets passed
• behavior tests cover nbands_sto syntax and boundaries, all, valid and invalid spin, solver compatibility, process limits, and kpar * bndpar divisibility
• the migrated noncollinear integration reference records the reproduced C_4h magnetic point group
• generated metadata contains 519 parameters and matches the checked-in Markdown
• repository governance check passed
